I

After metal reinforcing rims l8 are secured in place the blank is bent up to form a tubular body which constitutes the side walls of the container. Such a tubular body may have flat side areas, as indicated at 36 and 38 in Figures 2 and .3, joined by curved or rounded corner portions, as indicated at 40, or maybe continuously curved as is the side wall 42 of Figure 4. When the blank IQ of Figure 1 is shaped to form a container having alternate flat and curved side wall portions, as illustrated in Figure 2, the tab portions will lie along the flat areas of theside walls and may be discontinuous over the curved areas, as is clearly indicated by the tab portions 20, 22 and 24 in Figure 2. If it is desired to provide additional support around the curved portions of the container, the material between the fiat portions illustrated in Figures 1 and 2 may be die-formed into substantially sector shaped tabs, as indicated at 44 in FigureB, whereas, if the container is to have a continuously curved side wall to provide a cy-- lindrical shape of circular or elliptical cross-sec-' tion, the tab strips are divided into a pluralityof relatively short ta'b members having inclined edges, as is particularly illustrated at 46 in Figure 4.

When-the blank wtih the reinforcing rims applied along the'edges thereof is bent into tubular form, the tab members will lie along the inner surface of the tubular body thus formed and will be rigidly supported on the side walls by the clamped on reinforcing rims I8. Rims I8 substantially maintain the given tubular body shape of e the container, and their ends are suitably secured in overlapped relation-so that they are substantially continuous. When it is desired to apply the end closure as- 1 the closure assembly. Also, if desired, the two complementary member is then inserted beneath the tabs at the opposite side of the container and caused to adhere thereto. During this application of the two parts of the end closure assembly, the container end tabs, one of which is indicated at 22 in Figure 2, may be bent upwardly out of the way to the necessary extent. After both members of the closure assembly have been inserted and secured to the corresponding tabs at the opposite sides of the container, the end tabs may then be forceddown and caused to adhere to the contacting surfaces of both parts of parts of the end closure assembly may be overlapp d. is clearly indicated at 58 in Figure 2.. a

and the adjacent surfaces may be caused to ad here together by the application thereto of a suit- I able glue or cement.

The .end closure assembly shown in Figure 3.

may be inserted in the same manner as described above in connection with Figure 2 in order to close the container after it has. been filled. In this case both the end tabs and the triangular or sector shaped corner tabs can be bent upwardly semblies to the tubular body of the container, the

tabs are first bent outwardly until they project inwardly of the tubular body and are substantially perpendicular to the inner surface thereof.

After the tabs are bent out, as indicated by the broken line position in Figure 5 and by the full line positiondllustrated in Figures 2, 3 and 4, an end closure member is inserted into the contain- 5 er and brought to rest against the inner surfaces 1 ,of the tabs.

may be inserted before the container is filled or One of the end closure assemblies packed and may conveniently comprise a single piece of the same class of material ofwhich the side wall blank I0 is formed, as is particularly in- 5 dicated at 48 in Figure 4. When this piece of material is brought to rest against the tabs at the corresponding end of the tubular body, the

member or assembly by the use of a suitable glue or cement between the tabs and member 48.

As it is somewhat difiicult to insert the opposite end closurerafter the container has been- 1 vfilled, it has been found convenient to provide an end closure assembly of two or more parts, as in- 1 dicated at 5B and 52 in Figure 2 and 54 and 56 in Figure 3.

In the arrangement shown in Figure 2, the two 3 parts of the end closure assembly each have an area somewhat greater than one half the area until the two parts of the end closure'assembly are positioned beneath the side tabs and then may be bent downwardly and caused to adhere to the two parts of the end closure.

In the form of the invention shown in Figure 3, the two parts of the end closure assembly do Q not overlap but approximately abut along the center portion of the container-end. The crack or opening between the adjacent edges of the end closure parts may be sealed by applying thereto an adhesive material such as a gummed strip 50 V of paper or other material such as Scotch tape. Also, if desired adhesive material such as gummedkraft paper, as indicated at 62, may be applied over the end closure pieces and the associated tabs in order to provide a neat and substantial end closure'for the container..

This arrangement provides a neat and rigid container in which the ends thereof are protected and reinforced by the metal rims so that the tabs are caused to adhere to the end closure container does not depend for strength and rigidity upon the end closures thereof. The end closures may thus be formed for convenient assembly rather than for strength since they are not only relieved of any load incident tofiieformation of the container but are also protected. by the metal rims which extend beyond them at the corresponding ends of the container. The end closures may also be conveniently inserted by hand at the time the container is filled or packed, and

no cumbersome or expensive machinery is re-' quired for closing and sealing the containers. If desired, the blanks ill for the particular kinds of containers may be shipped in a fiat condition to save shipping space and may be conveniently bent by the user to the desired shape and the ends secured together as is more particularly set forth in our Letters Patent No. 2,359,335. The end closure assemblies may also be shipped in a fiat condition disassembled from the container and it is not necessary to apply either of the end closures until such time as the container is to be used. The invention thus provides an extremely economical container which may be easily assembled, closed and sealed by the user at the time the container is filled or packed. i

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the

United 1. In a container. a single sheet of flexible material bent into hollow tubular Ionn with its ends secured together to define the container side wall, a plurality of flaps disposed interiorly of said eonwhich provides bent away from {imam scope of the invention being indicated by the appended claims scription, and

meaning and range of equivalency of the claims are therefore intended to be embraced therein. a

What is claimed and,desired to be secured by States Letters Patent is:

tainer along the edge of said side wall at one end of said container, a relatively rigid reinforcing rim strip extending about and along said edge of said side wall. said rim strip being shaped longitudinally to follow the contour of said side wall edge and being transversely'bent into generally c-shaped cross section for enclosing said edge with its opposite lateral edges tightly embedded in the material of said flaps and said container side rather than by the foregoing deall changes which come within the ,wall respectively and haying its opposite ends disposed to form a substantially continuous bead an inwardly projecting marginal shoulder around said one end of said container; and said flaps inwardly of said rlm strip being the plane of said side. wall so as to form flanges proiecting from the inner surface of said container side wailinwardly of said marginal shoulder,

comprising a plurality of separate members closure means or said one end of said container disposed inwardly of said flanges.

sure members comprising having their adjacent portions overlapped and and means for securing said closure members to said flanges, said closure members seating along their outer surfaces directly upon the dances and having adjacent portions secured together.

- 2. In the container defined in claim 1, means disposed on the outside surfaces of said closure members for sealing the joint between adjacent closure members.

3. In the container defined in claim 1, sheet sealin material adheslvely. secured across the entire exposed external surfaces of said closure members and overlying said head.

4. In the container defined in claim 1, said clofiat plate-like elements secured together.
